" Specification of Letters Patent. Patented Aug. 22, 1922.

Application filed November 12., 1919. ets No. 337,4 0.

To all to hom it may concern:

Be it known that I, FREDERICK WINKLER, a citizen of the United States, and a resident of Bloomfield, county of Essex, and

State of New Jersey, have inventedcertain rotate, as such barrels usuallyare, to cause the articles placed therein to be tossed and to agitate in contact with one another and, if need be, with other articles introduced in the barrel so as to provide a smooth finish on the articles.

The invention is designed to provide a barrel which causes the articles to be finished more quickly, since they pursue a longer path when being rotated in the barrel than if they were permitted simply to roll about circumferentially, this result being procured by the introduction of vanes within the barrel to cause the articles to be moved not only circumferentially, but transversely.

The invention is further designed to provide a barrel of this kind which has an annular chamber between the inner and outer shells so as to more definitely move the contents of the tumbler in a circumferential directio'n.

The invention is further designed to provide a barrel of this kind which can be used in wet tumbling, permitting the introduction and withdrawal of water, so that the articles in the barrel are cleaned, the dirt being forced off with the water, and the outlets of the water pipe that feeds Water to the device are not in a position to be clogged by dirt, being kept from contact with the contents of the barrel. p

The invention is illustrated in the accompanying drawing, in which Figure 1 is a simple vertical section of the barrel with the inner shell shown in elevation, and Figure 2- is a vertical section of the barrel.

The barrel is mounted in any usual form of bearing in which it can rotate, the form shoWn illustrating a stud 10 on one end and a collar 11 on the other end, which are adapted to fit in a bearing and support the casing, which consists of an outer shell 12 and an inner shell 13 and the end plates 14: and 15. The space between the inner and outer shells forms a chamber 16, which is annular and into which the naterials' or articles to be tumbled. or polished aredeposited. a

To permit such introduction of the articles I provide a door or lid 17 adapted to be secured in placeby a s;uitable catch 18, although other locations for the door for the introduction of theflarticles can be provided.

It will be evident that as the barrel is rotated, articles 'within' it are carried" around in the circular chamber, and to insure such carrying I provide vanes 19 projecting from the inner shell a radial directlon, but being inclined fromopposite which the articles are successively passed and thus forced to move not only circum-" ferentially, but transversely, so that in a 20, which are preferably inclined in the same direction but in the oppositedir'ectionto the vanes on the inner shell, so that the articles that rest on the bottom part of the chamber are not permitted to remain there, 1

but are carried around in the barrel.

If desired, the barrel can be equipped for wet tumbling, a pipe 21 being introduced through the center of the barrel with its innerend enclosed in the chamber 22 within the inner shell 13, the enclosed end of the pipe being perforated, as at 23, so that water can be caused to flow from the openings 23, which are preferably downwardly directed, and then pass through the openings 2 1 in the inner shell 13 into the chamber 16, and pass from the chamber 16 through the openings 25 in the outer shell.

This water carries with it the dirt from the articles in the barrel, and there is no necessity for any other washing of the articles j and the barrel does not require any cleaning out. In the form shown I provide a. trough 26 which encloses the lower part of the barrel to provide for an economy of water, and a suitable outlet pipe 27 is provided so that the water can be with- '70 sides in the same direction, as will be clearly evident from Figure 1, so that a series of hopper-like receptacles are presented into drawn from the trough When desired, or it can act as a constant drain if that is preferred.

The form of the barrel can be varied according to circumstances,-'but I prefer to make it as illustrated, that is, of a polygonal shape,whereby more abrupt changes in the direction are given to the articles Within the barrel than are provided With a round barrel, thus further contributing to the more rapid completion of the tumbling operation. .l claim:

1. A tumbling barrel comprising a polygonal inner shell, a polygonal outer shell, end Walls, all combining to form a polygonal annular chamber, vanes extending from the end Walls along the inner shell and part Way across, these vanesbeing inclined circumferentially in the same direction, and vanes extending from the end Walls along the outer shell and inclined cir'cuinferentially in the same direction, but

opposite to the direction of inclination of the first mentioned vanes.

2. A tumbling barrel comprising apolygonal inner shell, a polygonal outer shell, end Walla-all combiningto form a polygonal annular chamber, vanes extending from the end Walls along the inner shell and part Way across, these vanes being inclined circumferentially in the same direction, vanes extending from the end Walls along the outer shell and inclined circumferentially in the same direction, but opposite to the direction of inclination of the first ,mentioned vanes, the inner and outer shells being perforated, and a pipe acting as an axle to the barrel and having perforations, whereby Water can be projectedthroughthe perforations in the inner shell and pass through the chamber and the perforations in the outer shell.

In testimony that I claim the foregoing I have hereto set my hand, this 10th day of November, 1919.

FREDERICK WINKLER.
